Libtiff 3.9.0 is now released. Please read about it at http://www.remotesensing.org/libtiff/v3.9.0.html.
This document doesn't clearly answer the first two questions any packager will have about it, which are whether 3.9.0 is ABI compatible with 3.8.2, and if not how about source-code compatible? I could consider dropping 3.9.0 into Fedora 12 if it's ABI compatible, but if not it's probably too late...
Jay Berkenbilt (of the Debian project) expressed the opinion that it is ABI compatible with 3.8.2, that he had done testing in Debian experimental, and was planning to incorporate the code used to produce 3.9.0 into Debian.
Several changes since the 3.9.0Beta release were made with the objective that 3.9.0 be ABI compatible with 3.8.2. As with anything else related to free software, there are no No Guarantees. No one here gets paid enough to offer such guarantees.
